Background technology
In the oil and natural gas industry in this century, the quantity of the horizontal well of inclination increases, and the design strengthening productivity stratum drainage area becomes very complicated.It is believed that, horizontal well can have larger contact surface with rock stratum, which increases restorability coefficient and the inlet capacity thereof of the hydrocarbon of well.The hydrocarbon of this well flows into stimulate with structure, exploitation and keeps in repair all very different from the production of hydrocarbons technology by Vertical Well, and therefore, the stimulating method major part for Vertical Well is unsuitable for horizontal well.
Such as, horizontal well acidification to allow only to infiltrate in this stratum several meters dark, but most of spacing is still holed, the mechanical admixture, drilling fluid or other precipitate occlusion that detect and occur in production practice.
The method of prior art describes forces down-constrains pressure oscillation to stimulate bottom outlet region (the Russ P RU2276722C1 (2006) number of Vertical Well by physical field by means of generation; RU2310059C1 (2007) number; RU2373386C1 (2009) number).But due to plant bulk, concrete design feature and be transported in horizontal drilling hole, institute can not use in these processes in horizontal well.

As everyone knows, horizontal well drill through period, the porosity on bottom outlet stratum and permeability properties are affected by following factor: invade in drilling fluid stratum, invade in drilling fluid filtration beds, invade in cement filtration beds, boring destroys and parent rock condensation, infiltrate the mechanical admixture of stratum or the completion fluid blocked in boring or well killing fluid, in completion fluid or well killing fluid invaded formation, in stratum or boring, there is natural clay, paraffin and asphaltene precipitation thing cause formation blockage, in stratum or boring, there is saline deposit, stratum emulsification and use mechanical admixture injection solvent.
All above contents all cause bottom outlet permeability to reduce, and therefore, cause production capacity to be generally about 60% of design, and in a worst case scenario, if infringement is very dark, then causes well to be produced and stop completely.
The method proposed that entering hydrocarbon in horizontal well stimulates not only allows to warp (cleaning/dredging) shank (shank) operation room distance especially, and allow to use previously lost and the retention areas of bad discharge and ore bed.This maximises environmentally perfectly operating of well, and in all stages of the life cycle from exploitation, not by means of fracturing and acid bath.Along with the reduction of the well productivity ratio during well operation, the method proposed can repeat stimulation process several times, until well operates in viable economically.
